Abstract: 1458754 Gas turbine plant FRANCE ARMED FORCES MINISTER OF 25 Nov 1974 [4 Dec 1973] 51017/74 Headings F1G and F1L [Also in Division F4] A power unit including an internal combustion engine 1, a turbo-compressor supercharging unit 2, 3 and an auxiliary combustion chamber 5, is operated by injecting fuel into chamber 5 through an injector port 13 to be mechanically atomized when injected at a maximum rate, and continuously blowing air into a zone 9 of the chamber close to the port at a rate sufficient for the air to pneumatically atomize the fuel when supplied at a minimum rate. Air from the compressor 2 is supplied to the Diesel engine 1 through a cooler 4 and also to the combustion chamber 5 through a bypass 6 and primary or secondary air passages 8 and 10. Liquid fuel is pumped to injector 24 by a pump 14 through valves 22, 27, controlled by a thermosensitive element 23, and a pneumatic actuator 20 respectively. Exhaust gas from primary air 8 is introduced into a zone 9, secondary air is introduced, along with the exhaust gases from passage 33 leading from engine 1, into zone 10, air is supplied to vaned nozzles 15 via a passage 18, and the combustion gases from chamber 5 are supplied to turbine 3. The primary and secondary air are regulated by a spring-urged piston valve 40. Several units 2, 3, may be grouped in cascade and the turbine and compressor may have several stages.

Title: Exposing articles to a source of ionising rays
IPC: G21K5/02
Filed: 1965-12-02
Abstract: 1,133,449. Irradiating packages. SAINTGOBAIN TECHNIQUES NOUVELLES. 2 Dec., 1965 [2 Dec., 1964; 27 Oct., 1965 (2)], No. 51228/65. Heading H5R. An irradiation device comprises a shielded chamber 10 closed on three sides with the entry/ exit means, e.g. cylinder 16, situated at the open side and operable so as to move containers into and out of the chamber. The radio-active source 34 is disposed in the vertical plane of symmetry of the chamber. Preferably, there are also means, e.g. roller chain conveyers 38, 42, for moving containers in closed circuit paths inside and outside the chamber. As shown, the conveyers consist of retractable catches 43 mounted on chains 42 which move backwards and forwards between the rollers 38. The cylinder 16 receives a container from the roller conveyer, then rotates through 180 degrees to deliver it to the chamber 10. The roller conveyer moves the container around the source 34 and back to the cylinder 16. The radiation source may consist of two (or a multiple thereof) panels of radio-active material, see Figs. 3-10, not shown. These panels are arranged to move in vertical but offset planes so that they are side by side in the source container (90) (below the irradiation chamber 10) but can be one higher than the other, or alternatively side by side or in an intermediate position relative to one another, when raised to their irradiation position. When more than two panels of radioactive material are used they may be arranged so that gaps between panels in the two vertical planes are not opposite one another, thus minimizing the influence of zones deprived of radio-active material. The source panels can be raised and lowered by chains or rods (98, 98a) which screw into one or both source panels. Preferably the total length of the source is less than that of the shielded chamber by at least twice the longitudinal direction of a container. The source container (90), see Figs. 2-4 (not shown), can be divided from the shielded chamber 10 by (a) a rotary cylinder (94) having a diametrical slot through which the source passes, or (6) two sliding inclined shutters. Electrical contacts can be provided at the ends of the paths of the source panels and at the end of the path followed by a hand crank controlling the rotary cylinder (94). These contacts prevent access to the chamber before the source panels are in their raised position and seal the source container (90) to the shielded chamber 10 when the panels are raised. The source container (90) is released only if source is in the container (90) and the source container shield (94) is closed. Radiation meters can be fitted in the walls and top of the shielded chamber 10, the latter being able to control access to the inside of the chamber. The total number and exposure time of the containers being irradiated can be controlled manually or automatically.

Abstract: 1444265 Discharging liquids from flexible containers W J JINOTTI 1 Nov 1973 [5 March 1973] 51667/73 Heading F1R [Also in Division A5] The apparatus comprises a first open box member 30 into which a similar member 50 is moved telescopically against springs 160 by an operating means e.g. a screw threaded shaft 140 engaging a nut 150 and rotated by a handle 100 to provide a space 170 for a fluid (e.g. blood) filled bag 180 between a wall 52 of the second box member and the adjacent lower wall of a frame 80 which encloses both box members. The nut is retained and prevented from rotating in a tube 70 of hexagonal cross-section attached to the wall 52 of the second box at its centre. A bearing 94 supports the thrust from the shaft via a hub 114 against the lip 92 of a depression in the wall 32 of the first box member. The hub is held towards the bearing by an annular member 130 so that when a blood bag is in position reverse rotation of the shaft removes the nut from contact with the lip 73 thus allowing the springs to apply force to the bag via the wall 52 causing its contents to be discharged from an outlet tube (not shown). A hanger (38) Fig. 5 (not shown) is secured outside the front wall 34 of the first box member and comprises a pivoted handle (42) in a frame (40). A rigid hanger (58) Fig. 4 (not shown) is secured to the wall 52 of the second box member. An electrically heated metal or plastics plate (164), Fig. 2 (not shown) may be hooked to the hanger (58), contacting and thus heating the bag. The box members and frame may be of metal or plastics.
